TYBOGBJAPHICAL MACHINE.

To all whom it may concern:

Be it known that I, CARL MUEHLEISEN, a citizen of the United States of America, residing at 23 Chausseestrasse, Berlin, N. 4, in the Empire of Germany, have invented new and useful Improvements in Typographical Machines, of which the following 1s a specification.

The present invention relates to improved means for inspecting the delivery mouth of and quick changing a magazine in a multiple magazine typographical composing and distributing machine. It is advantageously applicable to multiple magazine typographical composing, line-casting and distributing machines of the Mergenthaler type, commercially known under the trade mark Linotype, when it has a single fixed distributer behind the plurality of magazines and serving them all in turn through a pivoted magazine entrance, a set of escapements on each magazine, a single set of escapement rods to work any set of escapements and a single fixed assembler entrance in front of the said plurality, its escapements and escapement rods.

There are known at the present time, and in the machines of the type just defined, quick-changing means in which the plurality of magazines is supported upon a series of vertical cams symmetrically arranged thereunder and having their axes on a plane, parallel with that of the plurality, the socalled magazine frame upon which the magazine is so supported being provided with antifriction rollers engaging with the respective cams. It is also known to provide a single magazine machine of the said type, with a hand lever by which the op erator can raise the delivery mouth of that magazine high enough to allow him to inspect any part of its mouth, as when the delivery of matrices from any matrix channel may have ceased, such inspection being made from the front of the machine and over the assembler guide. It is also known to provide a double magazine machine of the said type with a similar lever for a like purpose, but the accomplishment of that purpose is limited to the top magazine of the two, because such lever cannot raise the bottom one high enough to expose its de livery mouth to inspection.

The present invention consists in the combination with such a plurality of maga- Specification of Letters Patent.

zines and magazine-supporting frame, of a hand lever capable of raising the delivery mouth of the lowest, and therefore of any, magazine in the plurality, high enough for any part of it to be so inspected by the operator. This capacity also provides for the front of the lowest, and therefore of any, magazine in the plurality, being raised high enough to be quick changed over the assembler entrance.

The accompanying figure is a side elevation of a preferred constructional form of the application of the invention to a machine of the type defined above. Referring to it, theplurality of magazines is represented by two, 1, 2, supported on the magazine frame 3, adapted to slide up and down in suitable guides on the machine frame as heretofore. Neither these guides nor the machine frame are included in the figure.

4: is the single fixed distributer; 5, the

magazine entrance pivoted at 6 on the machine frame; 7, one of each set of escapements; 8, one of the set of escapement rods; and 9, the fixed assembler entrance.

10 is the hand lever for raising the delivery mouth of the lowest magazine in the plurality, high enough for any part of that mouth to be inspected by the operator from the front of the machine. As the assembler entrance 9 is fixed in front of the delivery mouths of the magazines, it is obvious that that lowest magazine will not be high enough for such inspection until its bottom lip, 2'. e. the front edge of the bottom plate of that magazine, stands at a level above, and therefore clear of, the top of the assembler entrance 9. This lever 10 has its fulcrum 11 fixed on the machine frame, and its rear end pivotally connected to the frontwardly projecting arm of one or more angled links 12, having the top end of its, or tops of their, vertical arms pivotally connected, as indicated at 13, with a central point in the bottom of the frame 3 or symillustrated, each cam thereforeobvious that the lever 10. enables the operator to raise the delivery mouth of any-highest, lowest or any intermed1ate magazine in the plurality above the top of the assembler entrance 9. It is also equally obvious that such raising puts the front of.

the: highest, the lowest or any intermediate magazine in the plurality in position, so far as position with reference to the top of'the assembler entrance 9 is concerned, for being quick-changed over that entrance.

Any of" the known" devices for locking the frame 3 and plurality of magazines in their adjusted position with reference to the assembler and magazine. entrances 9" and 5, may be employed.

The mechanism for shifting the magazines'is as follows- 1-7 is a cam, or one of a series of cams, and 18 is a, or one ofa series of cams, behind the former and fast on shafts 1 9, 20,- j ournaled in. the machine frame. When there are only two magazines in the plurality, as is the case in the form has only a single rise, but each additional magazine requires an additional rise, thereby making the operat'ive edge of each earn a stepped one. Both cams or cam, series entrance 17' 18,are replicas of each other,.bothas to contour and angular position on their respectiveshafts.

21 is a hand lever fast on the front shaft 1?9 and projecting" to the front o-fthe machine within reach of the operator.

22 is a link from the front cam or ca1nseries 17 to the rear (more to make both turn together, when the The row of escapement rods 8 isembraced by a yoke 23 movable horizontally to and fro toaput the'noses of the said rods out ofworkingi connectionwith the escapements' 7 of the magazine to be changed and intoworking connection with those of the substituted magazine:

24 is a rearwardl'y extended framecarrymg the yoke 23 and adapted to move it as stated, by the engagement of an eye 25 at each end on a suitably supported horizontal rod 26. The frame 24 is moved by the front cam or cam-series I7, and to enable them to do that each is duplex inasmuch as it' has a special rise 27 for that purpose. As soon as the lever 21 is started, a rise 27 rocks thetop end of a lever 28 fui'crumed' on a stationary fulcrum 29- and in constant engagement with that rise, to the rear, bottom arm of the lever 28 push the frame 24 to the front, thereby disengaging the rods 8 from the escapements' be changed. This disengagement is accompanied by the rocking back of the magazine 5 on its pivot 6', which rocking back is effected by an arm 30 fast on the fulcrum 29, a second arm fast on the pivot 6, and: a

link 32 connecting their outer ends.

1 33 is an adjustable connection between the lever 21 is moved. 7

thereby making the 7 of the magazine to frame 24 andthe bottom end of the lever 28. There arenotches 34 in the rise 27 so positioned therein thatone' of them engages the top end ofthe lever 28 whenever the escapementrods- 8-are in working connection with a. row of escapements 7 and to lock them there;

The reversal of the lever starts the magazine frame 3 and as soon as the substituted magazine is in composing position, the magazine entrance 5; and the escapement rods 8" are returned to theiriworliing position and the former locked there.

Having described my invention, I declare that what I claim and desire to secure by' Letters Patent is 1. In a typographical machine, the combination of a plurality of magazines-,a frame carrying the magazines, means for shifting the frame to bring one or another of the magazines "ntooperative position, and further means for moving the frame and all of the magazines thereon as a whole from their shifted position to facilitate the removaf of the magazines.

2. In a typographical machine, the combination of aplurality of ma gazines, a frame carrying the magazines, means for shifting the frame to bring one or another of' the magazines into operative position, and further means for moving the frame from its shifted position to facilitate the removal of the magazines, the said'means comprising a hand lever fulorumed in the machine frame and connections between said lever the magazine frame. 7

3. In a typographical machine, the combination of a plurality of magazines, aframe carrying the magazines, means for shifting the finial-1e,to bring one oranother of the magazines into operative position, and further means for moving-f the frame-from" its shiftedposition to facilitate the removal of the'magazine's, the said means comprising a hand lei "er fulcrumed in the machine frame and angled link pivotally connected to the hand lever the machine frame respectively.

' 4. a typographical machine, the combination of a fixed assembler entrance, a"

magazines as a whole above the level of the assembler entrance for removal or inspection, and counterbalancing devices connected to said lifting means.

6. In a typographical machine, the combination of afixed assembler entrance, a plurality of magazines, means for moving the magazines vertically to bring one or another into operative relation to the assembler entrance, means distinct from the magazine moving means for lifting the magazines as a whole above the level of the assembler entrance for removal or inspection, and counterbalancing means to assist in the lifting of the magazines.

7. In a typographical machine, the combination of a fixed assembler entrance, a plurality of magazines, means for moving the magazines vertically to bring one or another into operative relation to the assembler entrance, means distinct from the magazine moving means for lifting the magazines as a whole above the level of the assembler entrance for removal or inspection, and means for counterbalancing the weight of the magazines when subject to the action of either of the two before-mentioned means.

8. In a typographical machine, the combination of a plurality of magazines movable as a whole to bring one or another into operative position, means for effecting such movement of the magazines, and means independent of such moving means for shifting the magazines as a whole from their moved position to facilitate their removal.

9. In a typographical machine, the combination of a plurality of magazines, a series of cams for moving the magazines vertically to bring one or another into operative position, and means for raising the magazines to an extent beyond that controlled by the cams.

10. In a typographical machine, the combination of a plurality of magazines movable vertically as a whole to bring one or another into operative position, means for effecting such movement, and independent means for moving the magazines as a whole to an extent beyond that controlled by the first means.

11. In a typographical machine, the combination of a fixed assembler entrance, a plurality of magazines, means for shifting the magazines vertically to bring one or another into operative relation to the as sembler entrance, and means for moving the magazines as a whole relatively to their shifting means to locate the lowermost magazine above the level of the assembler entrance for removal or inspection.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
